Activity operation的意思|示意

When a receive activity belongs to a request-response operation, a reply activity returns the output of the operation.

当接收活动属于请求-响应操作时，应答活动会返回操作的输出。

This restriction is different from the conflicting receive restriction, since a request-response operation is said to be active until the corresponding reply activity has been executed.

此限制与接收冲突限制不同，因为请求-响应操作在对应的应答活动执行完成之前都处于活动状态。

An invoke activity simply calls an operation on another service.

调用活动仅调用另一个服务的操作。

Each operation is an activity that might be performed.

每一个操作都是一个可以执行的活动。

The first operation the process receives wins, just like a plain choice activity, and the process follows its path.

流程接收的第一个操作会首先执行，就像普通的选择活动，并且流程会按照其路径运行。

This might be acceptable during short periods of heavy activity, but it should not be relied on for the steady-state operation of the server and its applications.

这在短期的大量活动时还可以接受，但要获得服务器及其应用程序的稳定操作状态，则不应依赖于此解决方案。
